In this new product the disconnectedportions 'of' the flavoring'material, having contrasting characteristics such as taste, color,appearancejtexture, density, etc., are relatively small: as compared to the total volume of the-finished product, but a the disconnected portions of flavoringmaterial,

Figure 3 shows in side elevation a modified form 01' pressure gun;

Figure 4 is a vertical section of a container filled with the product of my invention.

Referring to the drawing, there is shown in Figure 1 a conventional commercial basic substance freezer l for sherbet, ice milk, ice cream,

frozen custard and the like having a mix inlet 2 at the top and a partially frozen substance outlet at one end provided with a trough like inclined spout 3. The outlet is controlled by a slide valve 4 normally opened suiliciently to permit the partially frozen basic substance 5 to flow therefrom and down the spout in a flat stream that is of relatively slight thickness as compared to itswidth. Into this stream or mass of basic substance isinjected the flavoring material voring material-of a contrasting color to thebasic substance, which remains a liquid at normal temperaturesand attains the consistency of the bulk basic substance at refrigerating temperatures, being then a form retaining plastic that is deformable. By the term "form retaining plastie that is deformable I mean to indicate that the flavoring syrup material is subject to deformation in the same conventional manner as the basic substance, namely,.sherbet, ice milk, ice cream, irozen' custard, and the like at normal serving temperature. Thiszcharacteristic ises'- sential. otherwise the finished composite product could not bedipped or scooped .ior dispersing purposes from a. large container for sale in bulk form- V The flavoringmaterial Fis injected over the entire surface area oi. the mass of basic material 5, by discharging a plurality of spaced relatively short separate portions by a pressure gun 8. The gun 8 is'successively or-intermittently operable and moved or shifted after each discharge so each separate portion of ejected flavoring material is of substantial volume ascompared to particle size and arrangedv in spaced relation to other portions in the basic material. The flat stream offlavor material injected basic substance drops.

The flavoring material F is a liquid syrup flahole size.

same and gun 8. The outer end of the lever is has loosely pivotally connected thereto a depending valve stem l5 terminating in a conical valve It.

The nozzle of the gun is formed of an inner portion l1 and a detachably connected outer portion i8, each having an aligned passage l9, that also communicates with the barrel of the gun 8 when the nozzle is attachedthereto. In the inner portion I1 is a transverse opening terminating in a conical seat bis'ectin'g the passage 19 and adapted to receive the valve l6 to close said passage. This opening is closed by a plug through which the valve stem [5 passes.

With this arrangement the valve is normally closed and any flavoring material in the barrel of the gun 8 is retained therein. The gun may be successively or, intermittently operated by successive slight pressure of the thumb on the inner end of the valve operating lever B which will open the passage l9'as shown in Figure 2 and allow flavoring material under pressure irom the tank In tobe ejected from the nozzle into the partly frozen basic substance. The valve is only held open long enough to allow the ejection of a portion of flavoring material that will form in the basic substance an individual short sinuous Y portion of substantial volume as compared to par- Suflicient pressure is employed to inject each. portion of flavoring material into the mass 01' the partly frozen basic substance.

By shitting or moving and successively operating the pressure gun the entire surface area of the basic substance can be impregnated as shown in Figure .charge, the entire surface area of the-basic subfrom the spout into a container 1, breaking up into gobst during such passage. As it settles in the container theresult is .a bulk package of basic substance as shown in Figure 4 having grasped by the operator's hand and manually manipulated. The rear end of the gun is connected by a flexible tube 9 with a flavor'material container tank Hi to the top of which air. or

otherfluid pressure is applied from a source not shown, by the conduit ll.

Adjacent the front end of the gun 8 is an upstanding lug I2 to which is iulcrumed a lever I! with its inner end normally urged upwardly by an expansion spring [4 interposed between the l. By successivelyv operating the pressure gun and shifting or moving the same after each disstance canbe impregnated as shown in Figure 1. The relative movement between the pressure gun and the basic substance after each successive discharge will separate the individual portions oi fiavoringmaterial in' spaced relation to each other. The additional step of dro'ppin'gthe gobs of impregnated basic substance in the container will produce a helter-skelter effect in the final product; r

p In Figure .3 I have shown a modifiedform oi pressure gun comprising a cylinder 2| having therein a piston head 24 given a rectilinear movement through the cylinder by a rod 22 and handle 23. The outer end of the cylinder has a nozzle terminating adjacent an outlet pipe 26 from the container 25. The container 25 receives flavor, ing material of the character previously described. Upon operation of the piston in a manner wellunderstood, air from the cylinderis forced under pressure across the outer end of the outlet pipe 26, which will carry the flavoring material in the form of a spray to the basic substance to be treated. This flavoring material is under sufficient. pressure to inject in the plastic basic material. is successively and intermittently operated to inject the flavoring material in short spurts each containing suflicient volume of flavoring to form.

in the basic substance individual short sinuous portions of flavoring material or substantial volume as compared. to particle size. Due to the fact this method of injection employs the spray prin- -ciple the portions of flavoring material formed by each spurt will not be quite as dense as in 8 the basic substance mass being treated is in a flat On its forward'movement the piston i we at 32 nection with the flavoring and embedding successivre portions syrup material of contrasting characteristics and stance and assume the shape and have enough volume upon injection to described.v

When reference is made to normal temperatures, it is understood that I mean normal atmospheric temperatures as are found out-ofdoors in the summer time, viz. between 50 F. and 100 F. When reference is made to refrigerating temperatures, it is to be understood that I am referring primarily to temperatures below 32 F. The term specification is to be understood to define a change in state brought about by a lowering of the temperature as produce the product F., changing from a liquid to a solid state. I I

The term consistency as used hereinin conmaterial indicates that such material remains at degree of plasticity as the basic substance at cortemperatures, remaining separate and distinct and maintainingclear linesof'demarcation between the basic'substa-nce and the flavoring material at" all' such temperatures. The firmness and density may vary, but the same and basic substance is alwayssharp and di- 'tinct.
